Abstract

PURPOSE: To considerably improve the thermal fatigue resistance and impact toughness of the resulting sintered body by sintering a powdered mixture of a prescribed amount of a B1 type solid soln. contg. WC with Co-base Fe group metals under prescribed conditions.
CONSTITUTION: A powdered mixture of ≤80 vol% B1 type solid soln. (solid soln. of ≥1 kind of carbide such as TiC, TaC or NbC and WC) with Co-base Fe group metals is molded and sintered at 1,100W1,300°C at the beginning of N2 introduction under 0.5W50Torr partial pressure for starting N2 introduction or at ≥1,300°C at the beginning of N2 introduction under ≥50Torr partial pressure for starting N2 introduction. Thus, the surface part of the resulting sintered body has a larger amount of W solubilized in Co than the interior.
